Research

Aging in general—and age-related neurodegenerative conditions (such as Alzheimer’s disease) in particular—is associated with changes in cognitive and homeostatic function. We are interested in how brain regions and neuropeptides important for arousal and homeostasis (such as the hypothalamic orexin/hypocretin system) regulate the activity of the basal forebrain cholinergic system, which is classically associated with age-related cognitive decline. We combine anatomical, neurochemical, molecular and behavioral approaches to understand how these systems interact and how they change with aging. In addition, we use these same tools in collaboration with colleagues to study the neural underpinnings of stress and anxiety.
